I love the function to group tabs by AI. It's quite convenient and useful. Can I chat with a group of tabs? Sometimes I collect some solutions from different websites and would like to compare with each other.

@jachinshen
Thank you! Really happy to hear that! Cross-tab chat is definitely on our roadmap, you’ll be able to chat with an entire group of tabs once it’s released.
Super clean, and fantastic UI. Very helpful features. Love it!

@kl3jvi Thanks so much! Really glad you’re enjoying the UI and features, that means a lot to us!
I am using it for my Chrome for almost a year, its great to keep it organized. Would be awesome if its available to Safari also.

@endymion_cheung Thank you so much for using it for so long, really appreciate the support!
Safari support is something we’d love to add, but the current Safari extension framework doesn’t yet allow side panel extensions the way Chrome do. If Apple opens it up, we’ll bring Side Space to Safari as soon as possible.

@vouchy Thank you so much! Appreciate the support!
I absolutely love Side Space! Brilliant extension! Even if you are using an AI browser like Comet, the simplicity and utility of Side Space is a major productivity and organization boost. Great design and consistent improvement/iteration.

@sayyidalijufri Thank you so much! Appreciate the support!
Cool. Does your app track an alternative browser history? In Safari, there’s a bug—about once a year my tabs start partially closing without any way to restore them. It would also be really great to be able to search the history using AI; that’s very useful sometimes

@mykyta_semenov_ Thanks for your feedback! Our app currently supported chromium-based browser history but doesn’t yet support alternative browsers. and the current Safari extension framework doesn’t yet allow side panel extensions the way Chrome do. If Apple opens it up, we’ll bring Side Space to Safari as soon as possible.
